CEMENT BLOCK AND POST MACHINE.

To all whom it may concern.-

Be it known that we, COREY 0. WHITE and RAY WILCOX, citizens of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Cement Block and Post Machines, of which the following is a specification.

This invention relates generally to cement block and post machines, and more particularly to an improved construction of fastening device employed upon the corners of the flask or mold, the object being to provide a simple and efficient form of fastening means of such a character that the said flask or mold can be opened at one corner at a time without interfering with the other corners.

Another object is to provide a fastening device of such a character that when one is locked all danger of displacement is entirely avoided.

Another objectis to provide a fastener of such construction that when the same is opened it will cause the side and end of the flask or mold to simultaneously moveaway from each other, therefore leaving the corner of the block or post entirely free.

' With these various objects in view our invention consists, essentially, in connecting the bifurcated casting at the opposite ends of each end of the flask or mold and connecting castings at the opposite end of each side of the flask or mold, said last-mentioned casting having an arm adapted to project through the bifurcation of the first-mentioned casting and each arm having a lever pivotally connected thereto, said lever being also pivot ally connected to the bifurcated casting and provided with means for holding the parts in a locked or closed position.

The invention consists also in certain details of construction hereinaften fully described, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a top plan view of a flask or mold provided with our improvement, said flask or mold being used to make a flat block. Fig. 2 is a side elevation of the same.

In carrying out our invention we employ a flask or mold which may be made of wood or metal, as preferred, and the dimension of said flask or mold will depend entirely upon the character of the article it is desired to Specification of Letters Patent.

make. The flask or mold comprises the ends A, sides B, and base or bottom C, the same as usual. Upon the outer face of each end piece, at the end thereof, is secured a casting D, the end of which projects beyond the end of the flask, and such projecting portion is bifurc ated,as shown, and provided with outwardly-extending parallel lugs D. A corner E is secured at each end of each side of the flask or mold, said side castings each having an arm E, which is adapted to project beyond the end of the flask through the bifurcated end of the casting D.

The casting E is formed with a shoulder E a ainst which the overlapping ends of the end of flask rests, and the arm E extends over the end of this shoulder and is adapted to project through the bifurcated end of the casting D. An end lever F, bifurcated at F, is pivotally connected to the arm E adjacent its end by means of a pivot-bolt G, which passes through both members of the bifurcated lever and also through the arm E. The ends of the members of the lever are pivotally connected to the lugs D by means of the pivot-screw H, which passes through the said lugs and engages the bifurcated end of the lever upon the opposite sides thereof. This makes a double pivotal connection for the lever, one being between the lever and the arm E and the other between the lever and the lugs D, so that in reality the hand-lever is pivotally connected to both the side and end castings, the pivotal points being arranged as shown. It is obvious that when the lever is in the position shown in full lines in Fig. 1 the sides and ends of the flask will be securely locked together, and it will also be understood that when the lever is thrown outwardly to a position at right angles to its former .position, as shown in dotted lines in Fig. 1, both the sides and ends at that corner will be moved away from the molded mass, and it will also be noticed that the other corners of the flask or mold will not be disturbed.

For the purpose of locking the hand-lever when the sides and ends are in their closed position we employ the spring-latch I in connection with each lever, the end I of said latch working through the opening in the bifurcated lever and engaging the opening in the extreme end of the arm E. When it is desired to open the flask or mold, the springlatch is operated to unlock the lever, and the lever is then thrown around upon its pivot, thereby causing the end and side of the flask or mold to be moved away from the corner of the mass.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a device of the kind described the combination with end castings, said castings beingadapted to extend beyond each other, and a lever pivotally connected to the extending portion of one of the castings and also pivotally connected to the other cast 2. In a device of the kind described the combination with a casting adapted to be secured to the side of a flask and provided with a projection extending beyond the end of said side, a casting adapted to be attached to the 20 end of the flask and having a bifurcated end portion, a lever pivotally connected to the extended portion of the flrst-named casting and also pivotally connected to the bifurcated end of the second casting.

3. In a'device of the kind described the combination with the side casting having a projecting arm, of the end casting bifurcated and provided with lugs, a bifurcated lever pivotally connected to the arm, and also pivotally connected to the lugs and a springlatch for holding the lever in a locked position.
